Modular Rainwater Harvesting Tank

It is becoming increasingly obvious to municipalities across India that the cost of providing a usable water

supply is increasing rapidly. Decaying infrastructure and storm water system pollution is not only

contaminating ecosystems but this valuable source of water is literally going down the drain. Life Green

Systems Modular Rain Harvest Systems has solutions that can be tailored to your requirements for the

complete control of water, our most precious resource

Project Location: New Delhi

Date of Commencement: 14th April 2014

Date of Completion: 9th May 2014

Transformed a decade old conventional rain water harvesting tank into Life Green

Systems’ high efficient & innovative Modular Rain Water Harvesting for our client.

Life Green Systems has designed and developed modular rain water harvesting at client’s site based out

at Mansingh Road, New Delhi to facilitate the easy maintenance & re-ensuring the adequate

functionality. Our Modular Tanks are a crucial element of this execution.

This project makes use of:

Borewell – 02 Numbers.

Dual step filtration: - Desilting chamber then filtration tank

40,000 liters recharge Capacity

This system provides spatial flexibility to ensure maximum available water volume is captured and stored.

Rainwater can fall onto the courtyard, being filtered through the grass, soil, river sand and geo-textile layers

into the tank, clean as a whistle, ready for use.

Case Study

1. Cleaning of Existing RWH Pit & Desilting Chamber

2. Bore Well Installation

3. Construction of Modular Pit

a. Preparation of Sand Bed.

b. Placing of Geotextile.

c. Placing of Module Matrix.

d. Wrapping of Geo Textile & Stitching.

e. Filling of Sides with Sand.

4. Filter Installation

a. Dismantling of Floor PCC.

b. Filter Installation.

5. Connection of Filter to Existing Chamber.

Steps of Construction:

Step #1 Cleaning of Desilting Chamber

Step #2 Borewell Installation

Step #3 Geotextile Wrapping of Matrix Modules

Step# 4 Preparation of sand bed

Step# 5 Execution of Filtration tank

Why Our Modular Rain Water

Harvesting?

Unlike others, who offer individual

components, we provide end-to-end

turnkey modular rainwater harvesting

systems:

There is no need to source

individual components, perform

due diligence to ensure reliable

operation, or contact multiple

vendors for service and support,

Life Green Systems delivers the

complete modular rain water harvesting solutions along with consultancy

Dual Step Filtration through distillation chamber & filtration tank ensures the right water

quality for the intended end use

We hold the experience & expertise to design and develop the most-suited rain water

harvesting systems

Installations of high-end modular rain water harvesting systems

Recharge structure can be relocated easily. Tank can be relocated and size of tank can

be increased.

The site top surface can be used as various purposes like green area or parking lot

Water from top surface enters the modular tank after passing from soil, sand and geo-

textile. Therefore the quality of water getting recharged is good.

Together we can work to achieve water resource goals. We look forward to helping you

find your balance.
